If you encounter a grid configuration parameter error on your Hoymiles Inverter, check if the grid configuration parameter is correct and upgrade again. If the fault still exists, contact your dealer or Hoymiles technical support.
What to do if my Hoymiles MI-1500 shows a grid overvoltage alarm?
If the Hoymiles inverter alarm for grid overvoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm appears frequently, verify that the grid voltage is within the acceptable range. If it's not, you may need to contact your local power operator or, with their consent, adjust the grid overvoltage protection limit through the Hoymiles monitoring system.
What should I do if my Hoymiles MI-1500 displays a '10 min value grid overvoltage' error?
If the Hoymiles inverter alarm for 10 min value grid overvoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm appears frequently, verify that the grid voltage is within the acceptable range. If it's not, you may need to contact your local power operator or, with their consent, adjust the grid overvoltage protection limit through the Hoymiles monitoring system.
What should I do if my Hoymiles MI-1500 Inverter shows a grid undervoltage error?
If the Hoymiles inverter alarm for grid undervoltage occurs accidentally, it might be a temporary issue, and the microinverter should automatically recover once the grid voltage returns to normal. If the alarm appears frequently, verify that the grid voltage is within the acceptable range. If not, contact the local power operator or change the grid undervoltage protection limit via Hoymiles monitoring system with the consent of the local power operator. If the fault still exists, check the AC switch or AC wiring.
What should I do if my Hoymiles Inverter displays a grid overfrequency alarm?
If the Hoymiles inverter alarm for grid overfrequency occurs accidentally, it may be a temporary issue. The microinverter should recover automatically when the grid frequency returns to normal. If the alarm occurs frequently, check if the grid frequency is within the acceptable range. If it is not, contact your local power operator or, with their consent, change the grid overfrequency protection limit via the Hoymiles monitoring system.
What does it mean when my Hoymiles MI-1500 shows a 'Rapid grid frequency change rate' alarm?
If the Hoymiles inverter alarm for rapid grid frequency change rate occurs accidentally, the grid frequency may be abnormal temporarily and the microinverter can recover automatically after grid frequency becomes normal. If the alarm occurs frequently, check whether the grid frequency change rate is within the acceptable range. If not, contact the local power operator or change the grid frequency change rate limit via Hoymiles monitoring system with the consent of the local power operator.
What should I do if I suspect a power grid outage with my Hoymiles MI-1500 Inverter?
Please check whether there is a power grid outage.
What does it mean when my Hoymiles Inverter displays 'Port No input'?
If the Hoymiles Inverter displays 'Port No input', first confirm whether the port is connected to the PV module. If the PV module is connected, check the DC cable connection between this port and the PV module.
Why is my Hoymiles MI-1500 Inverter showing as offline?
If your Hoymiles Inverter is offline, first ensure that the microinverter is working correctly. Then, check the communication status between the DTU and the Hoymiles monitoring system, as well as between the DTU and the microinverter. If the alarm occurs frequently and cannot be recovered, contact your dealer or Hoymiles technical support.
What should I do if my Hoymiles Inverter displays an input port overvoltage error?
If your Hoymiles Inverter shows an input port overvoltage error, first ensure that the PV module's open-circuit voltage is less than or equal to the maximum input voltage. If the PV module open-circuit voltage is within the normal range, contact your dealer or Hoymiles technical support.
